Patent number: 11859507Abstract: A method and system for aligning a component within a turbine casing, and a related turbine casing. In a top-on position, a location of an optical target and another, vertically spaced optical target on the joint flange are measured. After removing at least the upper casing, the optical targets' locations are measured again, and the locations of a pair of reference points on an upper surface of the horizontal joint flange are measured. A prediction offset value is calculated for the component support position in the top-on position based on the locations. The prediction offset value may include a vertical adjustment based, in part, on a translation of a triangular spatial relationship of a number of the reference points and/or a tilt angle, a horizontal adjustment, and a horizontal joint flange surface distortion adjustment. Support position is adjusted by the prediction offset value to improve alignment.Type: GrantFiled: October 28, 2019Date of Patent: January 2, 2024Assignee: General Electric CompanyInventors: Krzysztof Andrzej Woszczak, William Patrick Rusch, Samuel Nathan Merrill, Ejiro Anthony Oruaga, David John Nelmes, Justyna Ludwika Wojdylo, John Francis Nolan

Patent number: 7617602Abstract: The temporary fastening system for joining upper and lower shell casings of a turbine to one another for maintenance purposes includes a stud/nut tensioning system employed in lieu of the conventional studs and nuts. Once the turbine is opened up and the inner shell and rotor removed, the upper and lower shell casings are temporarily secured to one another using studs received in registering openings in the horizontal flanges of the upper and lower shell casings and retainer plates serving as a stop for the stud/nut tensioning system. The tensioning system is hydraulically operated and avoids torsional force on the temporary studs. Once measurements are made, the turbine is again reopened and reassembled using the initially removed bolts or a third set of bolts to secure the upper and lower shell casings to one another.Type: GrantFiled: August 18, 2005Date of Patent: November 17, 2009Assignee: General Electric CompanyInventors: Philippe Jean-Marie Dupin, Dennis William Roberts, Andrew John Tomko, John Francis Nolan

Patent number: 7470109Abstract: Partitions have an airfoil coupled at opposite ends to inner and outer side walls. The side walls each mount radially extending male dovetails. The inner web and outer ring of a diaphragm include complementary shaped dovetail grooves. The male dovetails have reduced diameter portions while the female grooves similarly have corresponding reduced diameter groove portions. The male dovetails are inserted into the female dovetail grooves in an aft direction with stops of the reduced male and female dovetails preventing further movement aft. Seal welds are applied to prevent forward movement of the partitions relative to the web and outer ring.Type: GrantFiled: November 2, 2007Date of Patent: December 30, 2008Assignee: General Electric Co.Inventors: Andrew John Tomko, John Francis Nolan

Patent number: 7326873Abstract: Bucket tip tenons requiring refurbishment are removed from the bucket tips by grinding. Groups of buckets are clamped on a rotatable table in positions adjacent an induction heating coil and a robotic welding arm, respectively. While one group is preheated, the other group of buckets is in a welding location, enabling the welding head on the robotic arm to sequentially apply weld buildup material to the bucket tips. After applying weld buildup material in multiple passes and sequentially to the bucket tips, the buckets are removed, stress-relieved and the weld buildup material machined to provide refurbished tenons. Upon removal of the buckets from the table, the table is rotated to locate the preheated buckets in welding locations and additional buckets are clamped to the table for preheating.Type: GrantFiled: March 28, 2006Date of Patent: February 5, 2008Assignee: General Electric CompanyInventors: Todd Joseph Fischer, John Francis Nolan, Andrew John Tomko, Dennis William Roberts, Carter Steven Cook, David Roy Parker

Patent number: 6981836Abstract: A pair of stands are spaced one from the other to support opposite ends of an upper shell and diaphragm halves of a turbine at locations along the upper shell axially beyond the diaphragm halves. Carts mounted on wheels each have a hydraulically actuated lift and a platform mounting support assemblies engagable with an upper diaphragm half at the midline. By engaging a diaphragm half from below the upper shell, securing the support assemblies to the upper diaphragm half and releasing the upper diaphragm half from the upper shell by removing bolts and keys to transfer the weight of the diaphragm half to the cart, the diaphragm half may be lowered from the upper shell and moved away. The diaphragm halves may then be refurbished and the process reversed to reinstall the diaphragm halves into the upper shell. During the process, the upper shell remains in its normal orientation, similarly as in the turbine.Type: GrantFiled: April 28, 2003Date of Patent: January 3, 2006Assignee: General Electric CompanyInventors: Andrew John Tomko, John Francis Nolan, Karl Rudolph Anderson, III

Patent number: 6754955Abstract: Using sinker electrode discharge machining tools, damaged portions of partitions of the turbine which have been removed and replaced with weld material of increased thickness may be shaped and contoured to blend with the suction and pressure sides of the partitions. The diaphragm containing the partitions is located in a tank containing dielectric material. A numerically controlled EDM machine directs first and second sinker EDM tools having surfaces corresponding to designed surfaces of the trailing edge portions of the partitions applied to contour and shape the opposite surfaces of the weld material to blend with the pressure and suction sides of the partitions. A third EDM tool is used to shape the juncture at opposite ends of each partition with the arcuate surfaces of the inner and outer bands.Type: GrantFiled: January 30, 2003Date of Patent: June 29, 2004Assignee: General Electric CompanyInventors: Ralph J.
